PURPOSE:To improve the transfer efficiency of data by transmitting data in the form of a part of the own station data, a repeating signal, all data of other stations, a reset signal and the residue of the own station data respectively to give higher priority to the data transfer of other stations in case the data transfer of another station is received during the data transfer of the own station. CONSTITUTION:The data 2-2-1 of the data 2-2 on a slave station C of the data 2-3 sent via a synchronizing circuit 10 and an address detecting circuit 11 is supplied to a memory circuit 15-1 by a write signal W1. Then an address 6 is read out of an address memory circuit by a repeating signal, and a write signal W2 corresponding to an address (b) is read out of an information control circuit 14. Then the data 2-1 of the data 2-3 is written to a memory circuit 15-2 with the signal W2. Finally an address 2 is read out of an address memory circuit 13 by a reset signal 2-5 detected by a repeating/reset signal detecting circuit 12. Then the signal W1 corresponding to the address 2 is transmitted, and the data 2-2-2 of the data 2-3 is written to the circuit 15-1. |
